Chrysanthemum plant named &#39;Frosty Yocheryl

ABSTRACT

A new  Chrysanthemum  plant named ‘Frosty Yocheryl,’ particularly distinguished by the medium sized inflorescences with white colored mature ray florets, good floriferousness, dark green foliage with a well mounded plant habit, and a natural flowering season of early October.

Latin name of the genus and species of the plant claimed:Chrysanthemum×morifolium.

Varietal denomination: ‘Frosty Yocheryl’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Chrysanthemum, botanically knownas Chrysanthemum×morifolium, and hereinafter referred to by the varietyname ‘Frosty Yocheryl.’

‘Frosty Yocheryl’ is a product of a planned breeding program. The newcultivar has medium sized inflorescences with white colored mature rayflorets, good floriferousness, dark green foliage with a well moundedplant habit, and a natural flowering season of early October.

‘Frosty Yocheryl’ originates as a natural whole plant mutation of ‘CoolYocheryl,’ U.S. Plant Pat. No. 8,943. ‘Frosty Yocheryl’ was discoveredand selected by the inventor as a single flowering plant within apopulation of the parent cultivar in a controlled breeding program inAlva, Fla. in November 2006. The parent cultivar ‘Cool Yocheryl’ hasmore pink over-tones on a white flower, taller plant habit and has a fewdays faster flowering response.

The first act of asexual reproduction of ‘Frosty Yocheryl’ wasaccomplished when vegetative cuttings were propagated from the initialselection in November 2006 in a controlled environment in Alva, Fla.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plantinitiated in November 2006 and continuing thereafter, has demonstratedthat the combination of characteristics as herein disclosed for ‘FrostyYocheryl’ are firmly fixed and are retained through successivegenerations of asexual reproduction.

‘Frosty Yocheryl’ has not been observed under all possible environmentalconditions. The phenotype may vary significantly with variations inenvironment such as temperature, light intensity and day length.

Plant Breeder's Rights for this cultivar were applied for in theEuropean Union on Nov. 28, 2008 and in Canada on Oct. 30, 2009. ‘FrostyYocheryl’ has not been made publicly available more than one year priorto the filing of this application.

The following traits have been repeatedly observed and are determined tobe basic characteristics of the new variety. The combination of thesecharacteristics distinguishes this Chrysanthemum as a new and distinctvariety

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawing shows typical flower and foliagecharacteristics of ‘Frosty Yocheryl’ with colors being as true aspossible with an illustration of this type. The photographic drawingshows a flowering potted plant of the new variety, and a close-up of theflowers.

DETAILED BOTANICAL DESCRIPTION

The plant descriptions, measurements and aforementioned photographs weretaken outdoors in Gilroy, Calif. in late October 2009. These plants wereapproximately 12-14 weeks of age. The plants were propagated in Alva,Fla., then shipped to California at about 3-4 weeks of age, potted upand set outdoors in the trial.
